General Information

EC Number General Information Comment Organism
1.1.3.15 evolution enzyme glycolate oxidase, GOX, belongs to the gene family of (L)-2-hydroxyacid-oxidases ((L)-2-HAOX). In addition to GOX, plants possess (L)-2-HAOX proteins with different specificities for medium- and long-chain hydroxyacids (lHAOX), likely involved in fatty acid and protein catabolism. Vertebrates possess lHAOX proteins acting on similar substrates as plant lHAOX. The existence of GOX and lHAOX subfamilies in both plants and animals is not due to shared ancestry but is the result of convergent evolution in the two most complex eukaryotic lineages. Duplication and diversification occurred independently at the base of deuterostomia and at the base of vascular plants. The biological role of plantae (L)-2-HAOX in photorespiration evolved by coopting an existing peroxisomal protein, targeting sequences and predicted substrate specificities, phylogenetic analysis and tree, hypothesis for the evolution of the (L)-2-HAOX gene family, overview. Convergent evolution in vascular plants and deuterostomia Arabidopsis thaliana
1.1.3.15 evolution enzyme glycolate oxidase, GOX, belongs to the gene family of (L)-2-hydroxyacid-oxidases ((L)-2-HAOX). The encoding gene is thought to have originated from endosymbiotic gene transfer between the eukaryotic host and the cyanobacterial endosymbiont at the base of plantae. Animals also possess GOX activities. Plant and animal GOX belong to the gene family of (L)-2-hydroxyacid-oxidases ((L)-2-HAOX). In addition to GOX, plants possess (L)-2-HAOX proteins with different specificities for medium- and long-chain hydroxyacids (lHAOX), likely involved in fatty acid and protein catabolism.
